I ran across a great follow-up to a story I wrote on Monday that detailed an increase in the level of investing in communications companies, which includes wireless, fiber and other telecom ventures, despite a five-year decline.

I wrote that the Venture One/Ernst & Young report showed Washington communications companies -- many of them developing wireless networks and services -- were on track to receive at least as much money this year as last, though there was a downtick this past quarter.

LightReading reported today that of the 39 digital media U.S. startups that received venture capital funding in the month of September, 15 are developing products and services around mobile devices.

The 39 funding rounds that took place during September raised $313 million, LightReading reported. Companies that develop technology that creates, enables, or delivers some kind of mobile content took $153 million of that.
